After listening to his explanation, Ah Chang basically understood the mystery.

It sounds magical, but is there any reasonable explanation for it now?

Lin Yi glanced back at him.

"I know you don't believe it, we can do an experiment, turn around and go back now, and when we get back here, this exit will definitely disappear."

After speaking, Lin Yi put away his notebook, picked up his backpack, and flashed a flashlight to return to the way he came.

Ah Chang lowered his head and followed in disbelief.

After they rounded an arc-shaped curve, they felt as if they had regained the feeling they had before, no matter how they went around, they couldn't get around, Lin Yi raised his wrist and glanced at the time, turned around, and stretched out his hand to point ahead.

"Let's go, it's time to witness the miracle!"

Ah Chang followed behind him, and the two of them quickened their pace and walked almost the same distance, taking about the same amount of time.

The exit that was supposed to appear in front of them just disappeared.

Lin Yi reached out and tapped on the case of his watch.

"From the time we entered this labyrinth to the time you bungee jumping just now, there was an interval of about thirty minutes, which was almost the time for a stick of incense.

I think that these eight openings are not random, but have a fixed time pattern.

Just like the revolving door of a hotel, when the time comes, this exit will inevitably appear.

We walked for more than ten minutes just now, now stop and rest, and wait until about half an hour, continue walking, and the hole will inevitably appear! ”

As the minutes passed, the alarm set by Lin Yi rang.

He put away his notebook.

"Let's go, go over and have a look!"

The two of them quickened their pace, almost trotting forward, without reaching the entrance of the cave, Ah Chang could already feel the cold and damp air coming towards him.

This obviously confirms Lin Yi's thoughts.

"Boss Lin, I'm convinced!"

Lin Yi stood at the entrance of the cave and shouted loudly:

"Lao Wang, you haven't moved anywhere, have you?"

"Nope! I just don't know what's going on, this exit suddenly disappeared, and after about half a while, it reappeared. ”

"Does it feel familiar?"

Lin Yi asked.

Wang Qiang was pondering, and Bai Lu had already reacted.

"Brother Qiang, don't you think this looks like the cemetery mechanism we encountered under the Great Desert at that time?"

After Bai Lu's reminder, Wang Qiang immediately remembered the closing mechanism tomb road.

"I remember!"

"Think of this mechanism as a revolving door, which basically appears once every half an hour, and as long as it appears through the hole outside, there will definitely be a corresponding entrance inside.

But I still don't know which of the eight passages this entrance is.

Once we find this entrance, we will be able to move on to the next level. ”

Lin Yi told Wang Qiang the information about the elements that cracked this organ.

The problem now is that these channels don't seem to be connected to each other.

If there is a way to get to the passage next door, this problem will be solved.

"Do you think it's possible that we can find the same way back first?"

Qian Sheng came up with his own idea.

"But Brother Sheng, it's not like we haven't tried before, and after we go back, we will go back to the same place after going around."

Min Tun replied.

Wang Qiang suddenly stretched out his hand.

"Wait a while, I seem to feel a little bit, listen to me, when we came in, we went around an arc, and then we couldn't get out at all, plus what Lao Lin just analyzed, do you think this channel, it doesn't look like a Taiji diagram?"

"Taijitu?"

"That's right, it's the Taiji diagram, the passage is like the dividing line of the yin and yang fish in the middle of the Taiji diagram, after we come in from this end, go forward, pass through the center point, continue to go down, and we will arrive here.

But as soon as this place turns like this, we will be trapped inside, if we go like this, go back to the end of the entrance, will we be able to find the entrance to enter, and then we will find another entrance to enter, will we be able to find the exit? ”

As soon as Wang Qiang explained, what he said was like a tongue twister.

The four people around him all looked at him blankly.

"Brother Qiang, why don't you speak Mandarin."

"I speak Mandarin."

"But why can't we understand a word?"

Wang Qiang waved his hand.

"Well, it doesn't matter if it understands or not, just know the meaning. Let's go and explore the way. ”

After speaking, Wang Qiang got up and took the four of them to start walking along the road they came, pinching their watches and walking back.

According to Wang Qiang's inference just now, the time is calculated, and the position of the stop should be the position of the center of the Taiji diagram.

"This is a crucial step now, and if you want to connect with the road we came in, you have to stick to the wall on the left and keep going. Only then can you follow the dividing line in the Taiji diagram to the entrance. ”

After speaking, he took four people to cling to the wall on the left, lowered his head and walked forward, I don't know how many times he circled in it, just when the mobile phone timer began to remind, the hole when he came in before was indeed presented in front of several people.

"It's done! Brother Qiang, we're really on the right track! ”

"Brother Qiang, you're too good, what do you think of this method?"

"The puzzle that Brother Lin hasn't solved has been thought of, it's amazing!"

Several people praised one by one, which made Wang Qiang a little embarrassed.

"Don't don't, I'm lucky, my brain flashed out, and my ancestor appeared.

Now that we know the doorway here, next, the soldiers are divided into two ways, I follow Tiezi all the way, the third and Lulu take Min Tun all the way, if anyone finds the way down, come to the ground at the location of this entrance to make a big triangle mark, be sure to see the time. ”

Two groups of people, fifteen minutes later, drilled into the passage again.

This method of solving the maze is the most time-consuming, but now there is no other way out except this method.

And so it went on for hours.

Wang Qiang and Iron Hammer drilled into the passage for the second time, and according to the previous method, they successfully touched the exit, and told Lin Yi and them about this method.

When Lin Yi heard this, he instantly understood what he meant, and was full of praise for Wang Qiang's performance.

The two of them followed this method and returned to the entrance again, and then waited for the next change of the entrance to the cave as if they were waiting for a bus.

Unexpectedly, this time a huge triangular mark had already appeared in front of them.

This means that someone has already walked through this passage, and this passage can lead to the next level.

"Let's go, I don't know what to do if I don't go to the next shift!"

Lin Yi raised the flashlight and got into the passage with Ah Chang.

The situation inside looked no different than the other passages, until they reached the center of the circle on time, and finally a wooden staircase extended downwards in front of them.

There were already a few messy footprints on it.
